Desiccation of the Sahara since the middle Holocene has eradicated all but a few natural archives recording its transition from a “green Sahara” to the present hyperarid desert. Our continuous 6000-year paleoenvironmental reconstruction from northern Chad shows progressive drying of the regional terrestrial ecosystem in response to weakening insolation forcing of the African monsoon and abrupt hydrological change in the local aquatic ecosystem controlled by site-specific thresholds. Strong…

Environmental changes, climate and anthropogenic impact in south-east Tunisia during the last 8 kyr
Abstract. Pollen and clay mineralogical analyses of a Holocene sequence from Sebkha Boujmel (southern Tunisia) trace the climatic and environmental dynamics in the lower arid bioclimatic zone over
Abrupt Shifts in Horn of Africa Hydroclimate Since the Last Glacial Maximum
Quick-Dry Region The Sahara Desert is one of the driest places on Earth. However, 11,000 to 5000 years ago, it was a relatively lush region containing savannah grasslands and humid tropical forests.
Did pastoralism delay the collapse of the green Sahara 6000 years ago?
During the early Holocene, northern Africa was relatively humid and supported a large human population. Around 5,500 years ago (5.5 ka) the regional climate deteriorated and the population declined
Millennial-scale fluctuations in Saharan dust supply across the decline of the African Humid Period
Abstract The Sahara is the world's largest dust source with significant impacts on trans-Atlantic terrestrial and large-scale marine ecosystems. Contested views about a gradual or abrupt onset of
Holocene Hydroclimate Variability and Vegetation Response in the Ethiopian Highlands (Lake Dendi)
Northern Africa’s past climate is characterized by a prolonged humid period known as the African Humid Period (AHP), giving origin to the “Green Sahara” and supporting human settlements into areas
Aquatic community response in a groundwater-fed desert lake to Holocene desiccation of the Sahara
Abstract The finely laminated sediment record of a permanent, hypersaline, desert oasis lake in the Ounianga region of northeastern Chad presents a unique opportunity to document the hydrological
Towards an understanding of West African montane forest response to climate change
Aim Our aims were to provide a detailed chronology of past vegetation changes in the tropical mountains of west-central Africa since the Last Glacial Maximum and to discuss montane forest
Late Holocene plant and climate evolution at Lake Yoa, northern Chad: pollen data and climate simulations
Abstract. The discovery of groundwater-fed Lake Yoa (19.03° N, 20.31° E) in the hyperarid desert of northern Chad by the German research team ACACIA headed by S. Kropelin provides a unique,
Climatic change in northern Ethiopia during the past 17,000 years: a diatom and stable isotope record from Lake Ashenge
Lake Ashenge, a closed-basin lake near the northernmost penetration of summer monsoon rains, is well placed to provide a continental record of past changes in the strength of the African monsoon
The roles of fire in Holocene ecosystem changes of West Africa
Abstract The climate changes associated with the Holocene wet phase in the Sahara, the African Humid Period, are subject to ongoing debate discussing interactions between climate and vegetation and


Simulation of the Holocene climate evolution in Northern Africa: The termination of the African Humid Period
The Holocene climate evolution in Northern Africa is studied in a 9000-yr-long transient simulation with a coupled atmosphere-ocean-vegetation model forced by changes in insolation and atmospheric
Regime Shifts in the Sahara and Sahel: Interactions between Ecological and Climatic Systems in Northern Africa
The Sahara and Sahel regions of northern Africa have complex environmental histories punctuated by sudden and dramatic “regime shifts” in climate and ecological conditions. Here we review the current
The greening of the Sahara during the mid-Holocene: results of an interactive atmosphere-biome model
An asynchronously coupled atmospherebiome model was used to assess the biogeophysical interaction during the mid-Holocene, 6000 years before present. The model determines its own land surface
Simulation of an abrupt change in Saharan vegetation in the mid-Holocene
Climate variability during the present inter- glacial, the Holocene, has been rather smooth in compar- ison with the last glacial. Nevertheless, there were some rather abrupt climate changes. One of
Climate-Controlled Holocene Occupation in the Sahara: Motor of Africa's Evolution
Radiocarbon data from 150 archaeological excavations in the now hyper-arid Eastern Sahara of Egypt, Sudan, Libya, and Chad reveal close links between climatic variations and prehistoric occupation
The Holocene Asian Monsoon: Links to Solar Changes and North Atlantic Climate
A 5-year-resolution absolute-dated oxygen isotope record from Dongge Cave, southern China, provides a continuous history of the Asian monsoon over the past 9000 years, and shows that some, but not all, of the monsoon variability at these frequencies results from changes in solar output.
Late Quaternary Climate and Vegetation of the Sudanian Zone of Northeast Nigeria
Abstract The Lake Tilla crater lake in northeastern Nigeria (10°23′N, 12°08′E) provides a ca. 17,000 14C yr multiproxy record of the environmental history of a Sudanian savanna in West Africa.
Abrupt onset and termination of the African Humid Period:rapid climate responses to gradual insolation forcing

Southward Migration of the Intertropical Convergence Zone Through the Holocene
The Cariaco Basin record exhibits strong correlations with climate records from distant regions, including the high-latitude Northern Hemisphere, providing evidence for global teleconnections among regional climates.
Holocene Forcing of the Indian Monsoon Recorded in a Stalagmite from Southern Oman
A high-resolution oxygen-isotope record from a thorium-uranium–dated stalagmite from southern Oman reflects variations in the amount of monsoon precipitation, indicating that early Holocene monsoon intensity is largely controlled by glacial boundary conditions.
